Abstract

Traditional Information Retrieval techniques require documents sharing enough number of words in order to build semantic links between them. This kind of techniques is greatly affected by two factors: synonymy (different words have the same meaning) and polysemy (a word has several meanings, also known as ambiguity). Synonymy may result in loss of semantic difference, while polysemy may lead toward wrong semantic links. Stephen J. Green proposes the concept of synset (a set of words having the same or close meaning) and uses a synset method to solve the problem of synonymy and polysemy. Although the synonymy problem can be well solved, the polysemy problem remains, because it is not possible actually to use an entire document as a basis to identify the meaning of a word. In this paper, we propose a concept of context-related semantic set to identify the meaning of a word by considering the relations between the word and its contexts. We believe that this approach can efficiently solve the ambiguity problem and hence support automation of the Web document search and analysis.
